    Didn't expect that, the latest beta version even works with mods, that's amazing.

    Editing/saving works properly too, I'm sure there's a huge demand for this as people constantly need nbteditors for pixelmon. (Am I the only one thinking their nbt is a mess?)

    Thanks for updating this great plugin.

    @o0Julia0o: Go

    Change zombie health:
    /nbt id[Tab] HealF = 15.5
    Default zombie health is 20

    Set zombie health to maximum:
    /nbt id[Tab] HealF = this Attribues[0].base

    Change zombie maximum health:
    /nbt id[Tab] Attribues[0].base = 500

    select zombie as variable:
    /nbt %zomb select
    <then right-click on zombie>
    /nbt %zomb HealF = 1


    zombie base damage:
    /nbt %zomb Attributes[4].Base
    change base damage:
    /nbt %zomb Attributes[4].Base = 10
    zombie movement speed:
    /nbt %zomb Attributes[2].Base

    how can i change the health of a zombie?

    /nbt * Health = 1000

    and look at the zombie? What is the default-health? Can i change the damage, too?

    @Noxcode: Go

    Terrain control uses compressed nbt files with tag "Data"

    Use command
    /nbt $$chest = block
    And get file: plugins/PowerNBT/nbt/chest.nbtz
    chest export

  • Avatar of Noxcode Noxcode Jan 29, 2015 at 14:39 UTC - 0 likes

    hi, is it possible to export a chest block as a chest.nbt ?
    In the wiki of Terrain Control they said it exists a plugin to do that, which redirect me on this plugin but I didn't see the feature here.
    How can I do ?
    Thank you in advance

    @LucidTheStick: Go

    PowerNBT v0.8.2 beta

    Tested with:

    cauldron-1.7.10-1.1207.01.198-serverbug on edit chunk: blocks and entities not update

    bug on edit chunk: invisible players in all tested versions


    PowerNBT can parse strings in mojangson format.
    Restriction: mojangson value can not contain spaces that not enclosed in " "
    /nbt item = {display:{Name:"Item Name",Lore:["Item lore"]}}
    /nbt {a:12,b:14}

    Binary numbers

    Now you can input numbers in binary mode:
    /nbt b00000010 int copy

    Spawn entities

    Spawn entity:
    /nbt (object) (query) spawn [world]
    /nbt (value) spawn [world]
    Examples: /nbt {id:Pig,Pos[15d,100d,-32d]} spawn
    /nbt id123(Skeleton) copy
    /nbt buffer spawn
    tags id and Pos are required

    See full list of changes in changelog.

    @DPOHVAR: Go

    It broke a couple of plugins I use. I've been able to patch them but have had no luck with this one. It'd be great if you could as this will be the last Cauldron until something better comes along.

    @LucidTheStick: Go

    There are big problems with cauldron 1.7.10
    At this moment, this version is not supported
    I'll try to find a solution in the next update

    @WavyWonderz: Go

    There are currently no online version of javadoc
    You can generate it:

    git clone https://github.com/DPOH-VAR/PowerNBT.git
    cd PowerNBT
    mvn site:jar

    Can you post a link to a generated java doc for use in the IDE?

    Hey look! A pineapple!
